Smilodon diet has been generally hypothesized about, but is actually poorly understood in detail, especially because of the hot debate over feeding strategies. What is definitively known is that they ate prey from transitional areas between wooded and open habitats. Isotopic analysis on Smilodon teeth have concluded that their prey primarily ate open field grass, not other plant material such as berries or not, nor other meat. This is consistent with the ambush predator hypothesis, and is generally accepted. Thus, it believed that their primary targets were larger herbivores and may have included the local fauna such as deer, antelope, and horses (Meloro, 2011).
